The paper explores the spread of crop insurance (CI) in India and analyzes the association of factors affecting the demand for crop insurance. Additionally, using large farm-level survey data from Eastern India, the study assesses CI’s impact on rice yields of smallholder rice producers. The study tests for robustness of the findings after controlling for other covariates and endogeneity. Results indicate CI has a positive and significant impact on rice yields. In particular, the ATET and ATEUT effect of CI on rice yields is about 47%. However, CI’s impact on rice yields is heterogeneous among farm sizes of smallholders. Participation in CI increased rice yields of large farms by 49% but increased rice yields of small farms by only 16%.
